Currently there is development underway of a modbus master simulator.
  1. Modbus RTU
  2. Modbus ASCII
  3. Modbus TCP/IP (open mbus)
Commercial product intended as a compliance test and automated regression test typically for the development of embedded devices. I have done a number of test platform system integrations, so I'm going to roll all the experience into this product. I have reserved a new internet domain,, hosting will commence once the beta comes out.
